Default configuration

Default configuration Bubblewrap (bwrap) before version 0.4.1, if installed in setuid mode and the kernel supports unprivileged user namespaces, then the `bwrap --userns2` option can be used to make the setuid process keep running as root while being traceable. This can in turn be used to gain root permissions. Known affected systems include Debian testing/unstable, Debian buster-backports, Arch Linux using `linux-hardened`, and Centos 7 flatpak COPR. It has been fixed in the 0.4.1 release, and all affected users should update
